Shirley is organizing a Christmas party -- her first since her husband walked out on her -- and is eager to celebrate the season with the study group, her new family. However, her eagerness is sorely compromised by the fact that the religious beliefs of the other members of the group do not mesh with hers. Jeff, meanwhile, finds himself dealing with a local bully, Mike, who eventually gets him so riled that he challenges him to a fight, which causes problems; not only is it Jeff's first fight, but Shirley makes it clear that if he fights on what she considers a special day, he's no longer invited to her party.
